The Curse of the Petrified Forest...

Karma?

The Curse of the Petrified Forest:

In the Rainbow Forest Museum at Petrified Forest National Park, is a room filled with letters of repentent thieves. Heartbreaking, yet often hilarious confessions of those who picked up a piece of petrified wood in the park, only to regret it later. Some claim the rocks have ruined their lives. If you choose, you can sit in a chair and read any of the notebooks filled with the letters. Tales of divorce, ruined love lives, illnesses, unemployment, bad hair days, accidents, arrests and death...
